What is the minimum electrical current required to induce ventricular fibrillation in human subjects on cardiopulmonary bypass using different electrode systems?
Endocardial electrodes require the lowest minimum current (67 microamperes) to induce ventricular fibrillation compared to epicardial or intramyocardial electrodes in humans.
Watson et al. (1973) studied this question.
